Ccemented Carbide Cutting Tools Cutting Parameters

Cemented carbide cutting tool components:

1.Flank
2.Head - the cutting part of the blade
3.Tool tip - the main and secondary cutting edge Remit called the tool tip
4.Arbor - used for clamping

Cemented carbide cutting tool geometry parameters include the rake angle γ, declination and φ φ_1, after angle α, and the main edge bevel λ. It is reasonable or not directly affects the accuracy and surface finish, tool life and productivity of labor, as well as tool - parts - the machine tool system vibration resistance. Therefore, the selection of the most favorable geometry parameters is one of the important issues in the cutting. After the size of the angle, affect the frictional force between the rear workpiece. Friction is larger, the faster the tool wears. Tool flank wear after the angle is zero; friction and cutting temperature rise faster, the damage to the tool and more dramatic. Therefore, from the viewpoint of wear, it should choose the larger rear corner.

Cemented Carbide Cutting Tools Note

Cemented carbide cutting tools note:

• Cemented carbide cutting tool material is hard and brittle characteristics, it is sure to use a diamond grinding wheel finishing.

• Cemented carbide cutting tool materials having the hard and brittle characteristics, it will produce fracture when subjected to shock or the clamping force is too.

• Cemented carbide thermal expansion coefficient is small, it is used as a thermal sleeve or cold kits product, if the use temperature and the design value of a significant difference (high or low) will produce cracks.

• Note to be placed in a dry place, the storage of carbide cutting tools will make it corrosion due to cutting or other liquid, reduce tool strength.

• Hardness of brazing alloy blade brazing temperature is too high or too wet, will produce the blade off or cracks.

• Cemented carbide tool sharpening, you must carefully check whether the cracks.

• If electricity machining carbide cutting tools, tool surface should be checked for residual crack, otherwise it will affect the tool strength by fine grinding necessary to eliminate the tool surface cracks.

A base material of cemented carbide cutting tool

Metal cutting process, cemented carbide cutting tools cutting parts directly to complete the cutting work. Cemented carbide cutting tool material performance will directly affect the quality of the tool. Machining productivity and tool life of high end, the pros and cons of parts machining accuracy and surface quality largely depends on the choice of carbide cutting tool materials is reasonable.

Metal cutting process, cemented carbide cutting tools not only withstand a lot of cutting forces and high temperatures, but also to withstand shock loads and mechanical friction. Accordingly, the cemented carbide cutting tool materials must have a high hardness, high abrasion resistance, sufficient strength and toughness as well as good high-temperature heat resistance, chemical stability and thermal conductivity, and other aspects of performance. 

Cemented Carbide Cutting Tools Bue

Bue by the chip stacking a hard wedge near the cutting edge in front of the cemented carbide cutting tool, it is a region in the Cap II deformation zone (Section II deformation zone refers to the bottom of the chips in contact with the front of the cemented carbide cutting tool to produce plastic deformation) inside, is formed by the friction and deformation of the physical phenomena. In the production of medium carbon steel, mild steel, aluminum, plastic metal car, drilling, reaming, pull and thread processing may occur bue.

Cemented carbide cutting tool process basic law

Cemented carbide cutting tool is a cutting process by cutting movement, the cemented carbide cutting tool from the workpiece cut excess metal layer forming the surface of the chips and the machining process, in the course of deformation carbide cutting tools, forms a chip, resulting in cutting force, cutting heat and cutting temperature, cutting tool wear, and many other phenomena.

If you cut off the re-rolled in apple peel can also be joined together in accordance with the original look. However, metal cutting carbide cutting tools, especially in the continuous cutting of steel, the chip will not just roll up. Not because the chip is too hard, but because the chips will produce changes in the length of the reason. Meanwhile, the chip will be wider, thicker. That is, the cutting elements of different shape under different chips. The chip thickness is several times the original, while the length of the chip fraction of the original. Thus, a cutting speed obtained by cutting chips is equal to a fraction of the cutting chips produced.
